Core Issue
VG248 ports do not auto register to Cisco CallManager. If you try to register port 0 to represent port 1 on the VG248, the ports do not register successfully.
Resolution
Port 0 is used to integrate smdi-based voice mail systems.
To get ports to register, perform these steps:
- Delete port 0 from Cisco CallManager.
- Configure port 1 in Cisco CallManager.
- Disable or enable the correct ports on the VG248.
